The path followed by individuals in housing is dotted with experiences that may lead them to share domestic spaces and thus cope with the creation of a shared home. This article, the result of qualitative research with thirty people, seeks to grasp the implications and power games inherent in this process, within the framework of two particular types of shared living space: co-tenancy and setting up home together. While the former displays relatively little personal involvement, the latter is more emotionally charged and induces the partners to organize a set of strategies aimed at physically incorporating their individuality in the home.
